Sammy Forgit has discovered a vulnerability in Magix CMS, which can be exploited by malicious people to compromise a vulnerable system.
The framework/js/tiny_mce/plugins/pdw_file_browser/swfupload/upload.php script improperly validates the extension of an uploaded file. This can be exploited to execute arbitrary PHP code by uploading a PHP file with e.g. an appended ".jpg" file extension.
Successful exploitation requires that Apache is not configured to handle the mime-type for media files with a ".jpg" extension (configured to handle by default).
The vulnerability is confirmed in version 2.3.5. Other versions may also be affected.
Solution: Install patch. Please see vendor's advisory for more details.
